Is a Diesel Car Purchase Still Wise in 2026?

Not too long ago, diesel engines powered over half of India's passenger vehicles. Fast forward to April 2026, and the situation has significantly shifted.

With manufacturers like Maruti Suzuki, Honda, and Skoda-VW completely stepping away from diesel, your choices are now largely confined to heavy SUVs from brands like Mahindra, Tata, Hyundai, and Kia. So, is investing in a diesel vehicle still a wise decision?

If you regularly cover more than 2,000 km each month with long highway journeys, diesel still reigns supreme. Its exceptional low-end torque makes overtaking a breeze, and its highway fuel efficiency far surpasses that of petrol engines.

For larger SUVs such as the Mahindra Scorpio-N, Tata Safari, or Toyota Fortuner, diesel engines remain the most effective choice to manage their substantial weight.

Conversely, if your driving primarily involves congested city traffic, opting for a new BS6 Phase-2 diesel car could lead to significant headaches.

Frequent low-speed driving can block the Diesel Particulate Filter (DPF), and you'll often see warning lights prompting you to take a highway trip to clear the soot, which undermines the convenience of city driving altogether.

A major concern is the impact of government regulations. With the 10-year ban on diesel vehicles already in effect in Delhi-NCR, it's understandable that buyers in other major cities worry about similar policies being enacted nationwide.

This apprehension is already causing diesel resale prices to decline noticeably in the used car market when compared to Strong Hybrids.

Consider buying a diesel ONLY if you are looking at a heavy SUV (like the Safari or XUV700) and expect to spend 70% of your driving on highways.

For those seeking low running costs for city driving while also making some highway trips, it's best to bypass diesel altogether and invest in a Strong Hybrid or an EV.
